Probably you want to do something like this (pseudocodishly, I have not checked that this works): ;;; (define here-path (hash-ref metas 'here-path)) ;; `here-path` is an absolute path, so if your pagetree nodes are relative to project root, ;; you'll also want to make this one relative the same way. (require racket/path) ; for `find-relative-path`. (define here-path-relative (find-relative-path here-path (current-project-root))) ;; every node in a pagetree is a symbol (define here-path-pagenode (string->symbol (path->string here-path-relative))) ;; having made our special pagenode, now we can query the pagetree (define next-path-pagenode (next here-path-pagenode)) ;; then we convert the result back to an output path (define next-url (->output-path (build-path (current-project-root) next-path-pagenode))) ;;; BTW if the code above lives inside a template, use `local-require` rather than `require`. But I would put the code inside a function in "pollen.rkt". In that case you can pass `metas` as an argument, or use the `current-metas` parameter. -- You received this message because you are subscribed to the Google Groups "Pollen" group.
